How to log data from simulated LiDARs

Issue #10 closed

Hi, impressive work, thanks for sharing. I'm really a newbie at ROS and Gazebo, but I need velodyne simulated data for research purpose.

I would like to know if you can give us a simple way to record the simulated data in a text file ?

When the simulation is running I've tried :

rostopic echo /velodyne_points > test.txt

But it don't look like the best way to do it. Please let me know

    Thanks, but you might get better answers with a larger audience on

    The rosbag package can be used to record and playback any topic in ROS. There are several methods to convert rosbag files to csv files:

    It might be helpful to convert from a PointCloud2 to a PointCloud first:
